The Mean volumes can be used to help analyses of Frequency Decomposition blends in the Interactive Facies Classification tool (IFC+). By selecting a number of sample areas to identify different parts of a feature, it is possible to classify the geological event. In this case the feature below has been separated into 4 component parts; body of event (red sample areas), internal channels (blue sample areas), bright sections (green sample areas) and background (yellow sample areas). It is important to remember that a constant scaling factor has been applied to the frequency during the frequency decomposition process. For 16Bit data the scale factor is 10,000 and for 32Bit data it is 100,000.
The results from the test samples show the satellite area (pink) which has a bright response in the blend matches well with the bright samples within the main feature. From this we can conclude it may have a similar geological composition/fluid fill/porosity. Further correlation can be made between the northern extreme of the feature where both body (dark green) and channel (orange) test samples were collected and again match up with our earlier analysis. By running this style of analysis you may be able to better understand sediment distribution and reservoir quality within a feature to help make accurate interpretations for model building or STOOIP calculations.
